FIG. 2.

ΔsigB mutant exhibits greater specific growth rates than the wild-type strain in DM supplemented with different carbon sources in the presence of 0.5 M NaCl. Specific growth rates (SGR) of L. monocytogenes 10403S (open bars) and the corresponding sigB deletion mutant (shaded bars) in defined media supplemented with 0.04 or 0.4% (wt/vol) glucose (glu), 0.4% (wt/vol) mannose (man), 0.4% (wt/vol) fructose (fru), 0.4% (wt/vol) trehalose (tre), or 0.4% (wt/vol) cellobiose (cel) were determined. Cells were grown at 37°C in 96-well plates in the absence (A) and presence (B) of 0.5 M NaCl. The errors bars indicate the standard deviations from the means of triplicate measurements.
